That’s precisely the problem I had. After searching around for a while I found a solution that works using Bundler https://bundler.io/ Getting Gem with Dependencies: Create a new Folder with a File named Gemfile. Write a Source and the Gem you want to have the dependencies for into the File Example: source “http://rubygems.org” gem ‘rails’, … Read more
Solved it with help from my colleague. Turns out that the spec files have to be named with a _spec suffix, and bundle exec rspec spec works. I name the spec file with a test_ prefix previously. Was using bundler 1.3.5 and rspec 2.14.1
Constants in Ruby are nested like files and directories in filesystem. So, constants are uniquely identified by their paths. To draw an analogy with the file system: ::Rails::Engine #is an absolute path to the constant. # like /Rails/Engine in FS. Rails::Engine #is a path relative to the current tree level. # like ./Rails/Engine in FS. … Read more
Here’s the commit which adds the feature to rspec – This was on May 25 2008.

Remember that the ID is stored as :_id and not :id . There is an id helper method, but when you do queries, you should use :_id: User.where(:_id.in => arr) Often I find it useful to get a list of ids to do complex queries, so I do something like: user_ids = User.only(:_id).where(:foo => :bar).distinct(:_id) … Read more
Unfortunately open-uri only supports the GET verb. You can either drop down a level and use net/http, or use rest-open-uri, which was designed to support POST and other verbs. You can do gem install rest-open-uri to install it.
The debugger gem can be used but it still has issues. Install byebug which was written for Ruby 2.0 debugging. For breakpoints, use the byebug command in your code instead of debugger.
If you don’t want to spawn an array, there’s the conditional operator: max = a > b ? a : b
Sinatra and Rails use the path public for static content – e.g., ./public/javascripts/. All files in these paths would then be served by the web server (e.g. Thin, Passenger), but without the need for /public in the URL (e.g. the file at #{my_app_root}/public/javascripts/application.js would be available via the Web at the URL http://#{my_domain}/javascripts/application.js).
Inside the class itself: class_name = self.class On an initialized object named obj: class_name = obj.class
